DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1-5 The utility model provides a technical solution: an ink supply device for packaging printing, comprising an ink supply barrel 1; a switch mechanism 2 is provided on the ink supply barrel 1, a lifting mechanism 3 is provided on one side of the ink supply barrel 1, an ink supply tube 7 is installed on one side of the ink supply barrel 1, a pressure plate 4 is installed in the ink supply barrel 1, the ink supply tube 7 is switched on and off by the switch mechanism 2, and ink is supplied by the lifting mechanism 3;

[0024] In order to realize the function of opening and closing the pipeline, the switch mechanism 2 includes a switch chuck 200, which is installed in the ink supply tube 7, a limit rod 201 is installed on the switch chuck 200, a lever 203 is installed on the outer periphery of the switch chuck 200, a fixed protrusion 205 is installed on the inner side of the switch chuck 200, a connecting rod 206 is installed on the fixed protrusion 205, a baffle 211 is installed on the other side of the connecting rod 206, a fixed hole shaft 204 is installed on the baffle 211, an air valve pipe 5 is installed on the pressure plate 4, and a valve pipe 5 is installed on the air valve pipe 5. A valve rod 6 is provided, a hole is provided on the pressure plate 4, and the air valve pipe 5 is connected to the hole. A limit rod groove 202 is provided on the switch chuck 200, and the limit rod 201 is installed in the limit rod groove 202. A first connecting rod rotation hole 209 is provided on the fixed protrusion 205, and a second connecting rod rotation hole 210 is provided on the baffle plate 211. One end of the connecting rod 206 is installed in the first connecting rod rotation hole 209 through the first connecting rod hole rotation shaft 207, and the other end is installed in the second connecting rod rotation hole 210 through the second connecting rod hole rotation shaft 208. A lever groove 8 is provided on the ink supply tube 7. The lever 203 is installed in the lever groove 8, the baffle 211 is provided with a fixing hole 212, and the fixing hole shaft 204 is installed in the fixing hole 212. The ink supply barrel 1 is installed first, and the ink supply barrel 1 is placed under the pressure plate 4. The ink supply tube 7 is rotated first to make the air valve tube 5 in an open and closed state. When the pressure plate 4 descends, the air above the ink supply barrel 1 will be discharged first. When the excess air is discharged, the air valve tube 5 is closed through the valve rod 6 to prevent the dye from overflowing. At this time, the lever 203 is toggled again, and the lever 203 drives the switch chuck 200 to rotate. The switch chuck 200 rotates When the connecting rod 206 moves, it drives the connecting rod 206 to move. When the connecting rod 206 moves, it drives the baffle 211 to move, so that the baffle 211 rotates around the fixed hole shaft 204. After the four baffles 211 move away from each other, the ink supply tube 7 is unobstructed. The ink flows out of the ink supply tube 7 during the process of the pressure plate 4 pressing down. When the equipment stops working, some ink will remain in the ink supply tube 7. By resetting the lever 203, the baffle 211 is reassembled into a whole to close the channel in the ink supply tube 7, so as to prevent the internal ink from contacting the air and drying up and clogging the ink supply tube 7.

[0025] The working principle is as follows: first install the ink supply barrel 1, place the ink supply barrel 1 under the pressure plate 4, first rotate the ink supply tube 7 to make the air valve tube 5 in an open or closed state, the lifting motor 303 drives the screw rod 304 to rotate, and the screw rod 304 drives the connecting plate 305 to rise or fall when it rotates, and the connecting plate 305 synchronously drives the connecting rod 307 to move, and the connecting rod 307 drives the pressure plate 4 to rise or fall when it moves. Since the air valve tube 5 is in an open or closed state at this time, the air above the ink supply barrel 1 will be discharged when the pressure plate 4 descends. When the excess air is discharged, the air valve tube 5 is closed through the valve rod 6 to prevent the dye from overflowing, and then the lever 203 is toggled. The lever 203 drives the switch chuck 200 to rotate, and when the switch chuck 200 rotates, the connecting rod 206 is displaced. When the connecting rod 206 is displaced, the baffle 211 is moved, so that the baffle 211 rotates around the fixed hole shaft 204. After the four baffles 211 move away from each other, the ink supply tube 7 is unobstructed. The ink flows out of the ink supply tube 7 during the process of the pressure plate 4 pressing down. When the equipment stops working, some ink will remain in the ink supply tube 7. By resetting the lever 203, the baffle 211 is reassembled into a whole to close the channel in the ink supply tube 7, so as to prevent the internal ink from contacting the air and drying up and clogging the ink supply tube 7.

[0026] Example 2: Figure 1-3 In order to realize the function of automatic ink supply, the lifting mechanism 3 includes a lifting frame 300, the lifting frame 300 is installed on one side of the ink supply barrel 1, a lifting motor 303 is installed below the lifting frame 300, a screw rod 304 is installed on the lifting motor 303, a connecting plate 305 is installed on the screw rod 304, a connecting rod 307 is installed below one side of the connecting plate 305, a motor slot 301 is opened below the lifting frame 300, the lifting motor 303 is installed in the motor slot 301, a lifting slot 302 is opened in the lifting frame 300, and a screw rod 304 is installed on the lifting motor 303. The rod 304 is installed in the lifting groove 302, and a screw hole 306 is opened on the connecting plate 305. The screw rod 304 is installed in the screw hole 306. The screw hole 306 is threaded. The screw hole 306 is meshed with the screw rod 304. The lifting motor 303 drives the screw rod 304 to rotate. When the screw rod 304 rotates, it drives the connecting plate 305 to rise or fall. When the connecting plate 305 falls, it drives the connecting rod 307 to rise or fall. The connecting rod 307 synchronously drives the pressure plate 4 to rise or fall. The remaining features are the same as those in Example 1.
